Description

Technical Field

[0001] This utility model relates to the field of quality testing technology, and in particular to a wood strength testing device. Background Technology

[0002] In timber strength testing, angled or curved clamps are required for round timber, but these angles or curves can cause stress concentration in square timber, leading to distorted test data. Similarly, square timber requires a flat pressure plate, but round timber is prone to rolling and requires an additional anti-roll positioning device. Existing equipment requires frequent disassembly and replacement of clamp components based on the timber shape, such as replacing V-groove or flat pressure plate clamps, making its functionality limited. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a wood strength testing device.

[0004] To address the aforementioned technical problem that existing equipment requires frequent disassembly and replacement of clamping components based on the shape of the wood during wood strength testing, such as disassembling and replacing V-groove or flat pressure plate clamps, resulting in limited functionality in existing testing equipment, the technical solution adopted by this utility model is as follows: A wood strength testing device includes: a testing table, a strength testing component, and a clamping component; The strength detection component includes: a detection head; A power source is connected to the detection head for driving the detection head to perform wood strength testing; The clamping assembly includes a wood clamp, which is a combination of a V-shaped clamp and a flat clamp, and adapts to the clamping requirements of round or square wood through the V-shaped clamp and the flat clamp. An adjustment mechanism is connected to the wood clamp via a transmission, and is used to drive the wood clamp to rotate and adjust. A clamping power source is connected to the adjustment mechanism for driving the adjustment mechanism to clamp and position the wood to be inspected.

[0018] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0019] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0020] Please see Figure 1 - Figure 4 This embodiment proposes a wood strength testing device, which mainly consists of a testing platform 1, a strength testing component 2 located in the middle of the upper end of the testing platform 1, and clamping components 3 arranged on both sides of the upper end of the testing platform 1.

[0021] A detection chamber 101 is provided in the middle of the upper part of the detection table 1. This design allows wood chips and impurities generated during the detection process to be collected through the detection chamber 101. At the same time, a sealing door 102 is connected to the front end of the detection chamber 101 via a hinge. By opening the sealing door 102, the accumulated chips and impurities in the detection chamber 101 can be thoroughly cleaned.

[0022] The strength testing component 2 includes a top frame 201, which is securely mounted on the upper center of the testing platform 1 via welding or integral molding. A first hydraulic telescopic rod 203 is fixedly mounted through the upper end of the top frame 201, and a lifting plate 204 is fixedly connected to its lower telescopic portion. To ensure the vertical movement stability of the lifting plate 204, first sliding rods 205 are added to both sides of the upper end of the lifting plate 204. The upper ends of these sliding rods pass through and fit against the upper end of the top frame 201, thus limiting the vertical movement of the lifting plate 204. The testing head 202 is securely mounted on the bottom of the lifting plate 204 with bolts. As the lifting plate 204 moves downward linearly, the testing head 202 simultaneously compresses the wood downwards. A pressure sensor (not shown in the figure) is also embedded inside the testing head 202. This design allows for real-time and accurate detection of the pressure intensity generated when the testing head 202 compresses the wood.

[0023] The clamping assembly 3 includes side frames 301 welded or integrally formed on both sides of the upper end of the inspection table 1, wood clamps 302 for firmly clamping the wood, and an adjustment mechanism 310 capable of flexibly rotating and adjusting the wood clamps 302. The wood clamps 302 are a combination of V-shaped clamps and flat clamps, which can adapt to the clamping requirements of round or square wood. There are four side frames 301 in total, with two side frames 301 forming a group, and the two groups of side frames 301 are symmetrically distributed on both sides of the upper end of the inspection table 1. A second hydraulic telescopic rod 303 is fixedly installed through the upper end of each side frame 301, and both the first hydraulic telescopic rod 203 and the second hydraulic telescopic rod 303 are equipped with corresponding hydraulic control cylinders to precisely control their extension and retraction. The inner telescopic part of the second hydraulic telescopic rod 303 is fixedly connected to a U-shaped clamping frame 304, and a second sliding rod 309 is installed at the outer end of the clamping frame 304. The outer ends of these sliding rods pass through and fit against the upper end of the side frame 301, realizing the horizontal linear movement limit of the clamping frame 304. The adjustment mechanism 310 is located inside the clamping frame 304.

[0024] The adjustment mechanism 310 includes a motor 305 fixedly mounted on the lower end of the clamping frame 304. A worm gear 306 is fixedly connected to the upper drive shaft of the motor 305. The worm gear 306 is rotatably connected to the inside of the clamping frame 304 via a bearing seat. A worm wheel 307 is meshed with the side end of the worm gear 306. A drive shaft column 308 is fixedly mounted in the middle of the worm wheel 307. The wood clamp 302 is horizontally fixedly mounted on the outer curved surface in the middle of the drive shaft column 308.

[0025] Please continue reading. Figure 1In this embodiment, several opening slots 4 are also provided on the upper end of the testing table 1. These opening slots 4 are symmetrically distributed in sequence with the upper end of the testing table 1 as the center. The inner wall of the upper end of each opening slot 4 is rotatably connected to a support roller 401 through a rotating shaft. These support rollers 401 can provide rolling support for the wood on the upper end of the testing table 1, making it easy and convenient to push and transfer the wood on the upper end of the testing table 1.

[0026] In actual use, the wood to be tested is pushed onto the upper end of the testing table 1. Then, the second hydraulic telescopic rod 303 is extended synchronously through the hydraulic control cylinder, driving the clamping frame 304 to move inward, thereby allowing the wood clamp 302 to firmly clamp and position both ends of the wood. After clamping and fixing, the first hydraulic telescopic rod 203 is extended, driving the testing head 202 downward to perform precise compressive strength testing on the wood.

[0027] Simultaneously, before the wood strength test, the motor 305 can be activated to rotate the worm gear 306, which in turn meshes with and drives the worm wheel 307 to rotate. This causes the transmission shaft 308 to rotate the wood clamp 302, flexibly adjusting the horizontal position of the V-shaped clamp and the flat clamp to accommodate the clamping needs of round or square wood. This design not only enables the testing of the wood's compressive strength but also greatly improves the equipment's clamping and positioning capabilities for wood of different shapes, avoiding the cumbersome operation of frequently disassembling and replacing clamp components due to different wood shapes.

[0028] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
